I live in Point Cook and have to say that, having lived in other suburbs (including Rosebud), this one is by far the best. It's very family orientated, a lot of new developments going up so housing is modern and there is a good choice of rental properties to choose from whilst you search to buy or build. There is a high British population here too and some great groups on FB with regular meets so you can get to know people (pm me if you want the names of those groups).
Schools wise - there is a good range and I haven't heard a bad review on any of them. They recently opened a new K-9 school and there is land earmarked for a new P-9 too.
Have you been up here to visit? If not, I am happy to give you a tour one day.
